SHAFT-HANGER AND LUBRICATOR THEREFOR.

SPECIFICATION forming part of Letters Patent No. 553,676, dated January28, 1896.

Application filcdMarch 25, 1895. Serial No. 54=3,076. (N0 model.)

T0 on whom it may concern Be it known that I, JOSEPH E. HOPPEN, acitizen of the United States of America, residing at Newark, in thecounty-of Essex and State of New Jersey, have invented certain new anduseful Improvements in Shafting- Hangers and Lnbricators Therefor, ofwhich the following is a specification.

My invention has reference to improvements in the construction ofshafting-hangers and in means for lubricating the boxes thereof.

It has for its objects, first, to provide a hanger in which the box isreadily adjustable with respect to the shaft and in which all thedrip-oil is positively conducted to the drip-cup and prevented fromdropping to the fioor, and, secondly, to provide a detachable capillaryoil-cup for such hangers. To this end I provide the hanger with twoyokes having concave surfaces surrounding the journal-box, of which thelower yoke is provided with an orifice through which part of the wasteoil is discharged and through which the stem or nipple of a detachableoil-chamber provided with a drip-chamber is passed and connected to thebox.

The nature of my invention will best be understood when described inconnection with the accompanying drawings, in which Figure 1 is asectional elevation of a hanger embodying my improvement. Fig. 2 is avertical section in the plane 2 2, Fig. 1. Fig. 3 is a vertical sectionon an enlarged scale, part being broken away. Fig. at is abottom viewwith the oil and drip cup removed. Fig. 5 is a vertical sectionillustrating a spring wicktube for the oil-cup, part being broken away.Fig. 6 is a bottom view of the lower half of the box.

Similar letters of reference designate corresponding parts.

Referring now to the drawings, the letter A designates the base of ahanger.

B B are twoscrew-rods, the upper threaded ends of which are screwedfirmly into the base. At the lower ends of the sore w-rods are locatedtwo yokes O C properly bored out to pass over and be movable on thescrew-rods. The

yokes are provided with cavities c c, and the box D is provided withcorresponding convex portions (Z (1 fitting into said cavities in therespectively above and below the yokes.

yokes. These cavities and projections permit angular adjustment of thebox in a horizontal and vertical plane.

6 is a set-screw passing through the upper yoke and adapted to bescrewed down upon the box D for securing the same after adj ustment.

7 The yokes C C are adjusted vertically upon the rods B B and secured atthe proper height by means of nuts f located on the screw-rods In .thelower yoke is formed an orifice j, approximately below the center of thebox D, for the discharge of the oil which oozes from the joints of thesplit box. This orifice also serves for the passage of theattaching-nipple g of the combined oil and drip cup from which oil isfed by capillary action to the bearing. The nipple g is tightly screwedinto the upper part of a casting comprising the oil-chamber G and thesurrounding drip-chamber H. The oilchamber is provided with a series ofopenings 9 for filling the same. Within said oil-chamber. G andextending upwardly to the bearing of the shaft is located a wick I. Saidwick is encircled by a spiral spring J, which latter is compressed whenthe oil-cup is applied and holds the upper end of the wick constantly incontact with the shaft. The oil oozing from the ends of the box D isdirected to the dripchamber H by means of two downwardly-taperedtriangularly-shaped conveyers h preferably cast on the box and havingtheir inner and lower ends located above the drip-chamber. By the use ofthese conveyers I am enabled to employ a much smaller drip-cup thanheretofore.

The spiral spring J may be replaced by a split or perforated tube 1encompassing the wick and pressed upwardly by a spiral spring I attachedto its lower end and bearing against the bottom of the oil-chamber.

hat I claim as new is 1. The combination in a hanger, of a base, twoscrew rods secured to the base, two yokes provided with concave bearingsand adjustably supported on said screw rods; the lower yoke beingprovided with a vertical orifice, a journal box fitted to said concavebearings of the yokes, and provided with a vertical threaded opening, anoil cup provided with a nipple passing through the orifice in the lowerICO yoke and screwed into the journal box, and means for transferringthe lubricant from the oil-chamber to the shaft bearing, substantiallyas described.

2. The combined oil and drip cup for hanger or journal boxes hereindescribed, comprising a drip chamber, a chamber for the lubricantlocated centrally, and in its entirety within said drip chamber, aspring pressed wick placed within the lubricant chamber, and a nipplesecured to the lubricant chamber for the attachment of the combined oiland drip cup to the box, substantially as described.

The combination with a hanger or journal box provided on its bottom withconvey ers extending inwardly and downwardly from its outer edges, of adrip cup located below the conveyers, so as to receive the oil drippingfrom the inner ends of said conveyors, and an oil cup located within thedrip cup and provided with a wick for conveying the lubricant to thebearing, substantially as described.

4. The combination with an oil cup, of a Wick, a split tube encompassingand clampin the wick, and a spiral spring attached to the lower end ofsaid tube and bearing against the bottom of the oil cup for pressing thewick upwardly, substantially as described. I11 testimony that I claimthe foregoing my invention I have signed my name in presence of twowitnesses.
